The router uses AC or DC power. There are two load-sharing power supplies located at
the bottom rear of the chassis, as shown in Figure 2 on page 6. The power supplies
connect to the midplane, which distributes power to router components according to
their individual voltage requirements. When both power supplies are installed and
operational, they automatically share the electrical load. If one power supply stops
functioning for any reason, the remaining power supply instantly begins providing all the
power the router needs for normal functioning, and can provide full power indefinitely.
